How it works
- It calculates the container’s volume (as a cylinder) up to the fill line.
- It converts that to weight using the density of the wax you chose.
- Fragrance is calculated as a % of the wax weight.
- Buy 10% extra wax for pouring losses and the second pour.

Frequently asked questions
How much wax goes in a 7 oz (200 ml) jar?
About 6–6.3 oz (170–180 g) of soy wax, because wax weighs a bit less than water.
Why doesn’t wax fill the same volume as water?
Wax is less dense than water (about 0.86–0.95 g/ml), so 100 ml of wax weighs less than 100 g.
How high should I fill the jar?
Leave about 1/2 inch (1–1.5 cm) below the rim: it looks nicer and it’s safer.
